I've been playing with this mod in a save for a while now, and I think there's a bug that keeps most weapons, with the exception of the laser sword, from spawning. The laser sword is rare, but I've managed to get it a few times from trader ships. However, in the several years the colony has been going, never once has there been a trader who sold any weapon from this mod (with the exception of the sword), nor any of the weapons found on the raiders. I got curious, switched to devmode, and kept testing Pirate raid spawns with max raid points and reloading to see if I was just having bad luck, but the Mercenary Marine or any raider with any of these weapons never showed up, which I assume has to be bugged somehow.
